Yeah, I actually have a post about the upvote bots. Feel free to check it out on my blog as "The Epic Failure of Steemit, and Why you Should Care".
I would link to the article, but feel that doing so is a bit inappropriate to do in a completely unrelated post. A blog link on the other hand is less intrusive (in my opinion). If @stellabelle wants me to remove the link though, I'd be happy to.
Checked out the post you mentioned, and you chose a better way to mention it than just a blatent link, I/m sure many wold appreciate that.
